Permissions and groundwork in Welwyn Garden City
In Welwyn Garden City, work on adopted pavements and verges needs consent from Hertfordshire County Council, the local highway authority. Car parks, forecourts and other private land only need the owner's permission.
If your site in Welwyn Garden City is listed or inside a conservation area, check with the local planning authority (the council for Welwyn Hatfield) before choosing a finish — heritage settings often favour cast iron or painted steel over stainless.
Telescopic bollards need a deeper excavation than other manual bollards, so ground and services decide where they can go. Clay soils and high water tables mean a gravel base alone will not drain the cassette; a connection to a surface water drain or a separate soakaway is then needed, and foul drains are not used.
- Confirm the bollard is on your land; bollards on a public footway or dropped kerb need the highway authority's agreement.
- Leave access for emergency services on commercial and multi-occupancy sites, and record who holds keys.
What happens on site
Check depth and drainage
The free site survey checks how far down we can dig, where services run under the drive and how the ground drains. If water will stand, a drain connection is priced into the fixed written quote.
Form the drainage
A gravel soakaway is placed beneath the cassette, or a pipe is laid to a surface water drain or new soakaway.
Set the cassette
The cassette is set vertical and its top exactly at finished surface level and fall, then concreted in. A cassette set high or low is a common cause of tyre damage and trip edges.
Specification choices
| Option | Detail |
|---|---|
| Standard or lift-assisted | Lift-assisted models use a spring or counterweight so the post rises with little effort, useful for daily domestic use. |
| Reflective bands | Bands near the top help drivers see a raised post at night, particularly on drives shared with visitors. |
| Finishes | Galvanised, powder-coated in common colours, or stainless steel to suit the frontage. |
Pricing telescopic bollards in Welwyn Garden City
When we price telescopic bollards in Welwyn Garden City, these make the biggest difference:
- Stainless or powder-coated finish
- Drainage: simple soakaway or a connection to a drain
- Excavation depth and the presence of services under the drive
After installation
If the post becomes stiff or will not lower fully, the usual causes are debris in the cassette or a blocked drain, both of which are easier to fix early than after the post has seized. Lower and raise the bollard regularly, even if you rarely need to, so the mechanism stays free.
We can also service, repair or replace existing posts anywhere in Welwyn Garden City.

Will a telescopic bollard stop my car being stolen?
It adds a physical barrier that a thief has to defeat before driving away, which slows them down and makes the car a less attractive target. It is one layer of protection, not a complete answer to keyless car theft.
How deep does a telescopic bollard go into the ground?
Usually around the exposed height of the post plus the cassette base and drainage layer, which often comes to a metre or more. The exact depth depends on the model. That depth is why we check for services under the drive first.
